gap pad ? emi 1.0 is a highly conformable, combination gap flling material offering both thermal conductivity performance and electromagnetic energy absorption (cavity resonances and/or cross-talk causing electromagnetic interference) at frequencies of 1ghz and higher. the material offers emi suppression and 1.0 w/m-k thermal conductivity performance with low assembly stress. the soft nature of the material enhances wet-out at the interface resulting in better thermal performance than harder materials with a similar performance rating. gap pad ? emi 1.0 has an inherent, natural tack on one side of the material eliminating the need for thermally-impeding adhesive layers and allowing improved handling during placement and assembly. the other side is tack-free, again enhancing handling and rework, if required. gap pad ? emi 1.0 is supplied with a protective liner on the materials tacky side. note: to build a part number, visit our website at www.bergquistcompany.com. gap pad ? emi 1.0 typical applications include ? consumer electronics ? asics and dsps ? telecommunications ? pc applications configura tions available ? sheet form and die-cut parts pds_gp_emi 1_0515 features and benefits ? thermal conductivity: 1.0 w/m-k ? electromagnetic interference (emi) absorbing ? highly conformable, low hardness ? fiberglass reinforced for puncture, shear and tear resistance ? electrically isolating product description thermally conductive, conformable emi absorbing material may 2015 property imperial value metric value test method color black black visual reinforcement carrier fiberglass fiberglass ? thickness (inch) / (mm) 0.020 to 0.125 0.508 to 3.175 astm d374 inherent surface tack 1 1 ? density (bulk rubber) (g/cc) 2.4 2.4 astm d792 heat capacity (j/g-k) 1.3 1.3 astm e1269 hardness (bulk rubber) (shore 00) (1 ) 5 5 astm d2240 young's modulus (psi) / (kpa) (2) 10 69 astm d575 continuous use temp (f) / (c) -76 to 392 -60 to 200 ? electrical dielectric breakdown voltage (vac) >1700 >1700 astm d149 dielectric constant (1000 hz) 6.0 6.0 astm d150 volume resistivity (ohm-meter) 10 10 10 10 astm d257 flame rating v-o v-o u.l. 94 thermal thermal conductivity (w/m-k) (3) 1.0 1.0 astm d5470 thermal performance vs. strain deflection (% strain) 10 20 30 thermal impedance (c-in 2 /w) 0.040" 1.53 1.40 1.25 emi performance (astm d-5568-01 test method) absorption (4) db/inch db/cm @ 2.4 ghz -7 -2.8 @ 5 ghz -14 -5.5 1) thirty second delay value s hore 00 hardness s cale. 2) young?s modulus, calculated using 0 .01 in/min. step rate of strain with a sample size of 0.79 inch 2 . r elaxation stress @ 40 mil . 3) the astm d5470 test fixture was used. the recorded value includes interfacial thermal resistance. t hese values are provided f or reference only. actual application performance is directly related to the surface roughness, flatness and pressure a pplied. 4) based on waveguide testing with 60 mil thickness testing. typical properties of gap pad emi 1.0 0 1.00 3.00 2.00 4.00 5.00 6.00 140 120 100 80 60 40 20 0 thickness vs. thermal resistance gap pad emi 1.0 thermal resistance (c-in 2 /w) resultant thickness (mils) 01 32 45678 0 -2 -4 -6 -8 -10 -12 -14 -16 absorption and reflection (60 mil) gap pad emi 1.0 frequency (ghz) db
